Growth of iJatropha curcas/i L. fertilized with nitrogen and potassium under conditions of dry tropical forest of Colombia

Due to the demand in biofuel, the plant species that are not eatable and do not compete with traditional crops in Colombia, such as Jatropha curcas L., have become an important option. To produce more knowledge on the growth of this species, the research was carried out with different amounts of N a...
